SEPARABLE BUTTON.

SPECIFICATION forming part of Letters Patent No. 240,401, dated April19, 1881.

Application filed March 7, 1881.

To all whom it may concern Be it known that I, IRAD L. GARsIDE, acitizen of the United States, residing at Paterson, in the county ofPassaic, in the State of New Jersey, have invented certainnew and usefulImprovements relating "to Separable Buttons, of which the following is aspecitica tion.

My improved button somewhat resembles that described in the patent to medated July 27, 1880, No. 230,473, but is simpler, and on severalaccounts preferable. The shank is engaged by a pair of springs inclosedin the button and exerting a constant pressure toward each other.Theyare forced apart by the sh. nk, which is tapered for the purpose,and when the shank is sufficiently inserted they look under shoulders inthe shank. The shank is locked directly by the springs.

When it is desired to liberate the button from the shank it is effectedby a forcible turning of the button-body relatively to the shank. This,by the aid of a piece which is capable of tnrnin g partially within thebutton, or rather of remaining stationary with the shank when thebutton-body is turned, forces open the springs and induces theunlocking.

What Ihave termed a pair of sprin gs may be made in the form of a singlespring, if pre ferred. Iwillrepresentamodificationin which that form isadopted and several changes made in other parts.

The accompanying drawings form a part of this specification.

Figures 1 to 11, inclusive, are all different views of the whole, or ofparts in whatI esteem the preferable construction. Fig. 1 is a side viewof the button with its detachable part in place. I have added also asection of the front, which may be a polished stone, and of a rim, whichbinds the front tastily to what I have termed the body of the buttonproper. The parts which inclose the novelty are notin section, and arenot shown in this figure. Figs. 2 to 11 represent the parts whichcontain the novelty. Fig. 2 is a central section with the parts lockedtogether. Fig. 3 is a section on the line S S in Fig. 2. The relation ofthe parts corresponds to the view in Fig. 2. Fig. 4 is a (No model.)

front view of the body with the parts locked. Fig. 5 is a viewcorresponding to Fig. 3, with the body of the button turned relativelyto the shank sufficiently to unlock the latter. To effect this importantend the body is turned about an eighth of a revolution relatively to theshank, with the eftectofopening the spring sufficiently to liberate theshank. Fig. 6 is a section through the body with the mechanism removed,looking toward the back. Fig. 7 is a corresponding view, looking towardthe front. Figs. 8, 9, 10, and 11 are different views of a turningpiece, which is loosely fitted so as to be partially turned around inthe body. Fig. 8 is an edge view. Fig. 9 is a corresponding centralsection. Fig. 1.0 is a front view, and Fig. 11 is a section on the linet t. The remainin g figures represent a modification which involves someof the features of my invention, and will be described farther on.

Similar letters of reference indicate corresponding parts in all thefigures where they occur.

Referring to Figs. 1 to 11, A is a front and outer rim or shell of thebutton. A is a middle plate. A is a back plate and rim, formingajunction with the middle plate, A, and constituting therewith a box,which is received within the main shell A, and secured therein byforming over the back edge of the latter, as indicated in Fig. 1.

D D are springs, one end of each of which is fixed to the back plate, Aby encircling the respective pins (1. The springs are curved, as shown,and exert a considerable pressure inward by abutting against therespective pins (1. The ends D are straight for a considerable distance,and stand in the positions shown, pressing toward the center of thebutton. These portions Dof the springs form the looking means whichengage the shoe and shank to the button by locking under the shouldersof the shank.

B B, &c., indicate a turning piece. The

The hole in the middle plate, A, is mainly circular, but with a widenotch, a. This notch receives a narrower projection, B on thecorresponding part of the turning piece. The arrangement allows theturning piece to be rotated about one-eighth of a revolution, and thenforbids its turning any farther by the contact of the projection Bagainst one side of the notch a.

On opposite sides of the turning piece B are deep channels Z). This formallows the straight portions D of the springs to be received within theturning piece when the latter is in its usual position, but forces themoutward when the turning piece is sufficiently turned from its normalposition. The flattened portion B of the turning piece remaining betweenthe cavities b has a length equal to the whole diameter of the entireturning piece B. It performs the important function of forcing apart thespring ends when the device is turned and of receiving the force of thespring ends D in such manner as to compel its prompt return to itsoriginal position so soon as the turningpiece is removed.. A rectangularmortise, 1), extends longitudinally through the entire turning piece B.

G is a smooth round shoe. G is a fiat shank of a size adapted to beinserted through the mortise b, and having angular shoulders G adaptedto engage with the parts D of the springs. The shank G is beveled at itsfront end or head, so that on being inserted it can easily force apartthe spring ends D. So soon as the shank is forced fully home in the bodyof the button, or, rather, as the shank will usually be first insertedin the garment, so soon as the body is forced fully down upon the shank,the spring ends D, which have been forced apart by the beveled end ofthe shank, snap partially together, and engage strongly under theshoulders G and hold the body of the button firmly to the shank G andshoe G.

WVhen the shoe G and its attachments are held stationary and the body ofthe button is turned relatively thereto about one-eighth of arevolution, the form of the turning piece compels the spring ends D tomove apart, so as to disengage the spring ends from under the shoulders.Thus conditioned, the button may be detached; but under ordinaryconditions it is held firmly.

When the button is to be applied to a garment the shank is firstinserted through the button-hole from the back of the garment and causedto protrude at the front. Then the body of the button is applied in suchposition that the front end of the shank is received in the hole bin thecenter of the turning piece B, and the parts are pressed forciblytogether. The pressure inserts the shank into the body of the button byreason that the beveled front of the shank acts wedgewise to force apartthe ends D of the springs. So soon as the shank is pressed fully homethe tension of the springs causes their ends D D to engage unlike actionof the part B der the shoulders G of the head G The parts are now fullylocked, and the button is ready to serve for an indefinite period in theusual manner.

When the parts are to be disengaged the separation can be accomplishedby the partial turning ofthe body relatively to the shank, which willeffect the disengagement by forcing the spring ends D D out of contactwith the shoulders G of the shank G by the cam The proportions are suchthat the limit imposed 011 the turning motion prevents the possibilityof turning so far as to hold the spring ends permanently apart. So soonas the shank is withdrawn the force of the springs promptly returns theturning piece B B, 850., to its original position, ready forre-engagement of the shank in the manner first described.

Modifications may be made in the forms and proportions of the details.

It will be understood that the ornamental front A may be varied inmaterial, size, and pattern indefinitely.

One modification to which I attach much importance is shown in Figs. 12to 25, inclusive. Fig. 12 is a central section. Fig. 13 is a front Viewof the parts shown in Fig. 12. This shows them with the shank firmlylocked. Fig. 14 is a corresponding view with the shank partially turnedto effect its disengagement. Fig. 15 represents the same parts with themiddle plate inserted. Fig. 10 is a corresponding view, showing the twoparts of the button in the act of being detached by the shoe and shankhaving been forcibly turned relatively to each other. Fig. 17 is a frontview of the back plate and rim. Fig. 18 is a cross-section thereof onthe line 8 s. Fig. 19 is a front view of the middle plate. Fig. 20 is asection thereof on the line t t. Figs. 21 to 24, inclusive, representthe turning piece. Fig.2] is a front view; Fi 22, a back view; Fig. 23,a section on the line as as, and Fig. 24 a section on the line y 3 Fig.25 represents the spring detached. In these Figures 12 to 25, inclusive,a single spring serves the functions of the two springs employed in theother form. One point is held by solder E. The ends D of the springs arestraight and perform in the same manner as with the two springs. Theturning piece in this modification serves substantially as in the other,butis differently formed.

Parts of the invention may be used without the others. I can dispensewith the projections B and consequently dispense with the notches a inthe middle plate; but that would leave the device liable to be turnedtoo far,

7 and care would have to be exercised to avoid leaving the button withthe turning piece B B, &c., in the wrong position and with the springends permanently held apart.

I have termed the device a button, and esteem that the most convenientname, but it will be obvious that it can be made of small size, to serveas what are generally known as studs. It may be made in various sizesand materials, and serve for use or ornament, or

I both, in various positions.

I claim as my invention 1. In a separable button, the flat head G Ghaving a beveled front and shouldered back, as shown, in combinationwith the fiat shank G and shoe Gr, turning piece 13, and with abutton-body having springs arranged to be liberated by the turning ofthe parts relatively to each other as herein specified.

2. In combination with a button-body having springs, the turning piece BB, with cams B arranged to serve relatively to the spring ends D D, andto the shank-head G2 G and connected shoe G, as herein specified.

3. In a separable button adapted to be disconnected by the turning ofone part relatively to the other, the turning piece B B and project-ionB in combination with the plate A, 20 having the notched aperture a,arranged to serve relatively to each other, and to the shoe G, shank G,shank-head Gr G and locking devices D, as herein specified.

In testimony whereof I have hereunto set 2 my hand, at New York city,this 3d day of March, 1881, in the presence of two subscribingwitnesses.

I. L. GARSIDE.
